Every time I see this name, I want to pronounce it KIME (rhymes with dime), not KIM. While Kimberly/Kim isn't one of my favorite names, I don't really dislike it. This spelling just makes it look tacky, trendoid, and infantile.

In South Australia, Kym was a mainly masculine name. It entered the Top 100 in 1946 at #69, the same year Kym Bonython (born Hugh Reskymer Bonython in 1920), who was a prominent and active member of Adelaide society, was awarded the Distinguished Flying Cross. The peak year, by ranking, was in 1958 when it was ranked #13 (170 boys born with the name Kym), though the peak year, by number, was in 1959 when 179 boys were named Kym (ranked #14). It stayed in the top 100 continuously until 1985 (ranked #99), though the last time it was in the top 100 was in 1987 when it was in #86.

Kym, as a feminine name, entered the Top 100 in 1968 at #100 {22 girls} and the name went back and forth in popularity (#89 {29 girls} in 1971, #97 {23 girls} in 1973, #90 {25 girls} in 1975 and #98 {20 girls} in 1977) before falling down in popularity, beginning in the 1980s.
